Product Introduction – FHM Series Fiber Holder for Sumitomo T-81M / T-82M Ribbon Fusion Splicers
Overview
The FHM series fiber holders are precision accessories specifically designed for Sumitomo T-81M and T-82M ribbon fiber fusion splicers. These holders are used to securely clamp ribbon fibers (multi-fiber ribbons) during the splicing process. The FHM series includes multiple models to accommodate different ribbon fiber core counts, ensuring stable positioning, reducing splicing loss, and improving splicing efficiency for mass fusion of ribbon fibers.
Model Description
The model numbers FHM-4, FHM-6, FHM-8, FHM-12 indicate the number of fiber cores in the ribbon that each holder is designed to support:
| Model | Applicable Ribbon Core Count | Typical Use |
|---|---|---|
| FHM-4 | 4-core ribbon fiber | Low-core-count ribbon splicing, FTTA, indoor cabling |
| FHM-6 | 6-core ribbon fiber | Medium-core-count ribbon, common in access networks |
| FHM-8 | 8-core ribbon fiber | Standard ribbon fiber, widely used in backbone and metro networks |
| FHM-12 | 12-core ribbon fiber | High-core-count ribbon, high-density splicing, data centers, backbone |
All FHM series holders are manufactured to original equipment specifications, ensuring seamless compatibility with Sumitomo T-81M and T-82M fusion splicers.
Key Features
1. Precise Ribbon Fiber Clamping
-
Designed specifically for ribbon fiber geometry, ensuring all fibers in the ribbon are held in the same plane.
-
Precision-machined V-grooves or flat clamping surfaces prevent fiber misalignment.
-
Maintains correct fiber pitch (core spacing) for mass fusion, critical for low-loss splicing.
2. Optimized for Mass Fusion Splicing
-
Enables simultaneous splicing of all cores in a ribbon in a single arc discharge cycle.
-
Helps achieve typical ribbon splice loss as low as 0.05dB per core (single-mode) and 0.03dB (multimode).
-
Supports fast splicing cycles, typically 10–15 seconds for a 12-core ribbon.
3. Durable Construction, Easy to Use
-
Made from high-strength engineering plastic or metal alloy, resistant to wear and field use.
-
Easy to install: simply insert the fiber holder into the splicer’s holder slot and secure.
-
Compatible with Sumitomo’s standard ribbon stripping and cleaving tools (e.g., FHR-04, FCP-25).
4. Model-Specific Design for Different Core Counts
-
Each FHM model is precisely dimensioned for the corresponding ribbon core count, preventing incorrect usage.
-
Clear labeling on the holder body for quick identification.

Application Scenarios
-
FTTH / FTTx Access Networks: Splicing 4, 6, or 8-core ribbon fibers for distribution and drop cables.
-
Metro and Backbone Networks: Splicing 8 or 12-core ribbon fibers for high-density main cables.
-
Data Centers: High-core-count ribbon splicing (12-core) for high-density interconnect cabling.
-
Cable TV (CATV) and Local Area Networks: General ribbon fiber maintenance and installation.
Purchasing Recommendations
-
Select based on your ribbon core count: Match the FHM model to the exact number of cores in your ribbon fiber.
-
For standard access network work (4–8 cores): FHM-4, FHM-6, or FHM-8 are appropriate.
-
For high-density backbone or data center splicing (12 cores): Choose FHM-12.
-
If you work with multiple ribbon types, consider purchasing a full set (FHM-4/6/8/12) for maximum flexibility.
-
All holders are inspected for dimensional accuracy and surface quality before shipment.
